Application filed July 21,

To all whom it may concern:

Be it known that l, GEORGE W. WHITE- MAN, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Anticreeping Device for Rails, of which the following is a specification,

The tendency of railway rails to creep longitudinally especially on grades is the cause of constant trouble and expense since at comparatively frequent intervals it is necessary to shorten certain of the rails in order to make up for such longitudinal movement thereof.

One of the main objects of my present inventionis to design a novel construction of a device which will prevent such improper longitudinal movement of the rails after they are laid in the traclgand alsoto devise a construction which may be cheaply manufactured, and 'also be'durable and etficient in practice. v

To the above ends, my present invention consists of a novel construction of an antiereeping device for railway rails whereby any longitudinal creeping movement of the rail is prevented.

It further consists of a novel COI1StI{lCl3lOI1 of a tie plate and novel means carried thereby adapted to co-act with the base flange of the rail in such a manner that any creeping or longitudinal movement of the rail willcause such fastening device to bite into and more firmly engage the flange so that such longitudinal creeping of the rail will be positively prevented.

it further consists of a novel construction of a locking member which. prevents any lifting of the rail and which is mounted in such a manner that any longitudinal move ment of the rail causes such member to more firmly engage with the base flanges of the iail- It further consists of other novel features of construction all as will be hereinafter more fully set forth. v

For the purpose of illustrating my invention I have shown in the accompanying drawingsthos'e embodiments thereof which Willgive' in practice satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention, isnot limited to the precise arrangement and Patented March 2, 1909.

1908. Serial No. 4lM,583. 8

[ organization of those instrumentalities as 1 herein set forth. 5 Figure 1 represents a erspective view l showing an anti-creeping cevice embodying I my invention in operative relation with rel spect to a rail and the rail tie. Fig. 2 represents a plan view of the anti-creeping device seen in Fig. 1. Fig. 3 represents a secl ti'onal elevation on line xr, Fig. 2, of the anti-creeping device and showing also a portion of a rail in operative relation therewith. Fig. 4 represents a plan view of another embodiment of my invention in which two cam members are located on opposite sides of the rail for preventing any improper longitudinal movement thereof. Fig. 5 represents a plan view of another embodiment of my invention in which a plurality of cam members are employed to pre vent the improper longitudinal movement of the rails. Fig. 6 represents a sectional elevation on line y-y, Fig. 5, but showing in addition a portion of a rail in operative relation with respect to the anti-creeping device. Fig. 7 represents a sectional plan view of another embodiment of my invention. Fig. '8 represents a section on line zz Fig. 7 but showing in addition a portion of a rail in operative relation with respect to the anti-creeping device.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings:-l designates a portion of a railway tieto which my now "cl construction of tie plate 2 is adapted to be .securely fastened, it being noted that the tie plate 2 isprovided with depending lugs or projections S'which are preferably angularly inclined with respect to each other and which are adapted to en age and extend into the rail tie .1. when the evice is secured thereto.

l designates a flange or abutment preterably integral with the tie plate 2 and having its under surface 5 referably of suchcontour that the base dhnge of the rail 6 may enga e therewith. The rail 6 betof any usua or conventionaltype and in the present instance 1 have preferred to show the same as being of the usual l form of construction provided with. base flanges which are adapt ed to rest upon the tie plate 2 and to he socured thereto by means oi. the usual type'of fastening spikes 7 which pass through the tie plet'c2 into the railweytie 1.

being understood from Fi with suitable apertures 17 throug pensed 'jsimilar to the lug 8.

2 cla ses site to the gage with t e bearin lugs 24 and in this em bodiment, as seen in ig. 6, the inner bearing surface of the lug 24 is preferably concave as indicated at 25 as is also that portion of the cam members 21 which is adapted to engage with the base flange of the rail as is indicated at 26.

In the embodiments which I have thus far described the tie plate is placed in position on the. tie, as seen in Fig. 1, between the flange 4 and the locking member or members or between-the two locking members and the tie plate and the rail is then spiked to the tie.

In the embodiment seen in Figs. V and 8, l have shown a, slightly modified construction in which the tie plate Zis provided with a flange or abutment 4 in a similar manner to that seen in Figs. 1, 2, 3, 5 and 6, but in this embodiment I employ a movable locking member 27 which is provided with an extension 28, the latter being preferably provided with an irregular surface or serrations 29 rail as will be clearly understood by reference to Fig. 8. The operative surface of the projection 28 is preferably concave as indicated at 30 in Fig. 8. The member 27 is provided with a beveled or inclined side 3,1 which engages with the inclined face 33 which latter is preferably integral with the tie plate 2. It will be understood that in this embodiment after the rail has been placed on the tie plate 2 the member 27 is'forced forwardly, and since the flange 33 extends at an. angle to the 2, the irregular surface of the extension 28 will bite into and indent the base flange of the rail, thereby causing the same to be more firmly wedged between the locking member and the flange or abutment 4, thereby preventing improper longitudinal movement rthereo'l'.

it is to bodiments oiimy invention the locking memsurface adapted to engage the side bearing 7 the base I flange of the ran whereby any improper lifting or raising of the rail during the operation of trafiic 1s positively prevented.

present invention the tie plate is secured to and supported directly upon the railway tie and the rail is supported directly upon the tie plate and the fastening devices which secure the rail to the ties pass through the tie: plate and alsothe ties, so that ii the rail starts to creep the rail-Way tie itself must be moved but this is prevented by the ballast placed between the rail ties. It will further be apparent that in all the embodiments of my invention the further movement of the locking members after they have once been 8 designates a bearing lug or bracket located on the side opposite the-flange 4 and l preferably made integral with the tie plate 2. The inner surface of the bearing lug 8 is provided with a circular recess as seen at 9, it

. 3 thatthe inner face of this recess 9 is pre erably concave as indicated at 10 in Fig. 3.

11 designates a locking member having a bearing surface 12 whichbngages the concavebearing surface 10 of the lug 8.

13 designates a fasteningdevice such as a rivet, bolt or equivalent device which asses through the locking member 11 and t 1e tie plate 2, as will be clearly understood 'frorn Figs 2 and 3, so that the locking member is eccentrically mounted and forms a locking cam member. The member 11 is preferably provided'on its operative cam surface with the teeth or indentations '14 which-are adapt ed to bite into and indent the side of the flange of the nail, as will be readily understood by reference to Figsl and 3. i

In order to ositively revent any loosening of the loc ring mem er 11 after it has been fixed in position, it is advantageous in some cases to provide the same with a shoulder 15 between which and the lug 8 is inter posed. a spring 16 in order to prevent improper rearward movement of such. member 11 after the same has been placed in assembled osition with respect to the rail, althoug it is tobe understood that in many cases arising in nractice such spring 16 may be dispensed wit 1. The tie plate is rovided which the spikes 7 pass 111' order to fasten the tie plate to the railway tie.

In the embodiment seen in Fig. 4 l have shown a construction wherein l have diswith the flange or abutment 4 and emplo in lieu thereof a locking cam member 18 which is constructed in a manner similar to the cam 11, and I also employ a bearing lug 19 which is constructed in a manner A suitable fastening device-is also employed whereby when the rail is placed in positionon the tie plate 2 the' locking members 11 and 18 will firmly engage with the base flanges of the rail on opposite sides thereof.

In the embodiment seen in Fig. S'insteadl of employing a single cam member adaptiid to engage the flange of the rail on one side of the latter, I employ a plurality of suph members and in this embodiment, l ha've shown the same as consisting of a plurality of arms 21 the operative portion of which is preferably serrated or provided with an ir regular surface in order that a better grip on the base flange of the rail may be. obtained, it being seen that the members 21 are pivotally secured with respect to the tie plate 2 by means of suitable fastening deplaced in assembled position, owing to the vices 23, the end oi said members 21 oppo longitudinal movement oi" rail its-sir, mil
